Enhancement: accessibility improvements for tags, doc links, dashboard views

[shamoon]

Proposed change

I do like to support accessibility, this is some 'low-hanging fruit'. There are no visual (see unexciting screenshots because they look exactly the same as current) or functionality changes here.

• Use interactive elements (<button>) for remove 'x' for tags button & doc links
• Adds titles to the buttons in dropdowns (again, used by screen readers)
• Make tags on dashboard an interactive element (<a>)
• Add titles to interactive elements on the dashboard

Closes #6784
